SHUQUALAK, Miss —
A tornado also reportedly touched down Wednesday near Botkinburg in north-central Arkansas and injured four people, said John Robinson, the warning coordination meteorologist at the National Weather Service office in North Little Rock.
In South Dakota, snow and ice shut down several roads, including Interstate 90 for a time.
The weather service said the system could extend into flood-prone southeastern North Dakota, where about 3 to 5 inches of snow is expected through late Thursday.
"Any additional precipitation at this stage in the game is not necessarily a good thing," said Peter Rogers in Grand Forks.
